What is 27 percent of 31000000000 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 31000000000 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 31000000000 is 100%, so we can write it down as 31000000000=100%.
4. We know, that x is 27% of the output value, so we can write it down as x=27%.
5. Now we have two simple equations:
1) 31000000000=100%
2) x=27%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
31000000000/x=100%/27%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 27% of 31000000000

31000000000/x=100/27
(31000000000/x)*x=(100/27)*x       - we multiply both sides of the equation by x
31000000000=3.7037037037037*x       - we divide both sides of the equation by (3.7037037037037) to get x
31000000000/3.7037037037037=x
8370000000=x
x=8370000000

now we have:
27% of 31000000000=8370000000
